Had a quick question that I was curious about that perhaps some Oakley expert/insider might have an answer to that the community could benefit from knowing

Context: Now a days almost every new Oakley clothing piece comes with the regular tags that tell you what it's made up of (cotton, polyester, etc), how to wash it, etc. However, they also come with a tag that has a QR code that when you scan it takes you to a legit Oakley Site that "confirms" authentication like so:
My question is the following: If the oakley clothing you are purchasing contains this QR code and it displays the correct info for what you bought, does that pretty much confirm it is Authentic... or is this easy to do/counterfeit. Since it is just a QR code I imagine they can just copy and paste it and use it multiple times.
